To follow up on the filmstrip belt. No one makes them anymore for a replacement. And Lionel never stocks them. Maybe same supplier. I called all the parts sources from the different posts looking for the 464-41 and no one has it. I repaired mine with strips of duct tape and so far good. Anyone handy with making one from 8mm filmstrip and microscopic rivets I'm sure you could have a market I would buy 2. Thanks Patrick
